The present disclosure describes a method for treating mitochondrial DNA depletion syndrome by administration of a therapeutic amount of a composition comprising a dinucleotide compound or a mixture thereof. Further described herein are compounds, compositions and methods for the treatment of TK2 deficiency.

Described herein are Mpro cysteine protease inhibitors and methods of utilizing such inhibitors in the treatment of diseases, disorders, or conditions. Also described herein are pharmaceutical compositions containing such compounds.

Provided herein are methods and compositions for treating inflammatory disease by the administration, to a patient in need thereof, of an inhibitor of IL-2R desensitization in combination with a low dose of IL-2. A low dose of interleukin-2 (IL-2) is sufficient to stimulate regulatory T lymphocytes (Tregs) without substantially inducing effector T lymphocytes (Teffs). In some embodiments, the inhibitor of IL-2R desensitization is a small molecule or drug. Is some embodiments the inhibitor is a NEDD8 activating enzyme (NAE) inhibitor. In some embodiments a combination therapy provides for a synergistic effect, where the combination of the inhibitor of IL-2R desensitization and low dose IL-2 provides an effect that is greater than the sum of either the inhibitor or low dose IL-2 administered as a single agent.

Provided are medical uses and methods for targeting cancer stem cells employing ProTide compounds, particularly in the prevention or treatment of cancer. The ProTide may be other than one selected from the group consisting of: NUC-1031; a ProTide derived from cordycepin; and a ProTide derived from 8-chloroadenosine. The medical uses and methods for targeting cancer stem cells are particularly useful in the treatment of relapsed or refractory cancer in human patients. Also provided are methods of selecting patients who will benefit from prevention or treatment of cancer through the medical uses or methods of treatment of the invention.

The present disclosure relates to compositions and methods for treating retinal damage and/or retinal degradation. More specifically, this disclosure relates to methods for treating degradation of the retinal pigment epithelium by administering compositions comprising a nucleoside and/or a nucleoside or nucleotide reverse transcriptase inhibitor.

Compositions and methods of treating hyperglycemia in a subject having such a condition are disclosed. An inhibitor compound which causes activity of Cullin RING E3 ligases (CRL) to be reduced is administered to the subject, wherein blood glucose concentration is decreased. In at least certain embodiments insulin secretion and insulin sensitization in the subject are increased. Inhibition of CRL activity, e.g., by decreasing cullin neddylation by inhibiting NEDD8-activating enzyme (NAE), or decreasing cullin activity, e.g., by inhibiting expression of cullins, is shown herein to delay IRS protein turnover in liver cells and muscle cells, thereby increasing cellular response to insulin and decreasing blood glucose. Thus, inhibition of CRLs, for example by inhibiting neddylation, is an effective method to treat hyperglycemia and insulin resistance, and to increase insulin secretion in patients with hyperglycemia, for example due to type-2 diabetes.
